Gxss
Gxss is a tool to check a bunch of URLs that contain reflecting params.
This a light weight tool for checking reflecting Parameters in a URL. Inspired by kxss by @tomnomnom.
How It Works
- It takes Urls from STDIN
- It check for the reflected value on params one by one. (There are some tool like qsreplace which replace all params value but gxss checks payload one by one which makes it different from all those tools.)
For Example- Url is https://example.com/?p=first&q=second First it will check if p param reflects https://example.com/?p=Gxss&q=second Then it will check if q param reflects https://example.com/?p=first&q=Gxss
- If reflection for any param is found it tells which param reflected in response.
